Reminds me of the XGM mod, in that mod, the original phalanx formation was made somewhat loose and has more space between the pikes... The favt is, in this mod, you can break militia pikemen with Celtic Chosen Swords from the front without taking much casuality (but more elite and well trained pikemen didn't as easily... you'll suffer much casualities)

Now what about the sit down position and the Roman Triarii... They should sit when they are not in combat...
